I also forgot to mention. Would I multiply each segment afterwards with the rectangular or window function to obtain their respective windows?
Data segmenting with overlap and then multiplying each segment with hammond and rectangular window

Hello! This is currently my code:
[x,fs1] = audioread('Male1.mp3');
z1=x-mean(x);
t=(1:N)/10000;
z=x-mean(x);
w1=hamming(N);
w2= rectwin(N);
y=z.*w1;
figure;
plot(t,z,'k',t,y,'r');
xlabel('Time (s)'); ylabel('Amplitude');
figure;
y1=z1.*w2;
plot(t,y1);
It plots, but I want to overlap the data into 50 and 100 ms long overlapping segments. Would I have to use a buffer function? I'm not too familiar with Matlab. Thank you!

ok maybe I added some confusion in my last answers
the original question was simply to define overlapping sections of signal, not windowing and fft as with pwelch
